Just trying to get the word out about my new book Forensic Genealogy. Please visit our web site at www.forensicgenealogy.info
. There is a great chapter on DNA analysis - definitely a different approach. It has the basics for beginngers, but also has ideas on how to connect your family in a larger sense to world history - how to look at your STR results in the larger context both before and after surnames came into use. For example, through my DNA Fitzpatrick study, I have found evidence that might tie our family into survivors of the sinking of the Spanish Armada. It's for those of you who want to go beyond Most Recent Common Ancestor analysis.
The URL is www.forensicgenealogy.info
. There are Excel spreadsheets on the site that you can substitute numbers of markers, mutation rates, and numbers of mismatches to see the effect of each on MRCA calculations.
I will be glad to answer any questions that you migth have.
